The disagreement over nuclear inspections came as Iran’s president met with Pakistani mediators and technical teams from the U.S. and Iran continued talks in Switzerland.

A United Nations agency said Tuesday that a plan was underway to move stranded ships and their thousands of crew members through the strait — a vital passage for global energy supplies that Iran had blocked after the U.S. and Israel launched the war on Feb. 28.

Earlier in the day, a spokesperson for Iran’s Foreign Ministry, Esmail Baghaei, told reporters in Tehran that U.N. inspectors were not scheduled to examine nuclear sites bombed by the U.S. last year, rejecting comments made a day before by U.S. Vice President JD Vance.

President Donald Trump told reporters Tuesday that if Iran had not agreed to inspections, he would cut off talks with Tehran immediately. But he added there was no rush for those inspections to begin.

The International Atomic Energy Agency has not responded to requests for comment over its possible role. It has been in and out of Iran since Israel’s 12-day war in 2025, but has not been granted access to bombed enrichment sites targeted by the U.S.

Iran maintains that its nuclear program is for peaceful purposes, though it has highly enriched uranium that could be used to build atomic bombs, should it choose to do so, the IAEA has said.

The U.S. and Iran agreed to a deal last week that calls for Tehran to dilute its stockpile of enriched uranium, and waives U.S.-backed sanctions on the country while giving each side 60 days to hammer out broader agreements.

Plan to evacuate stranded seafarers through Strait of Hormuz

The plan to evacuate 11,000 crew members stranded on ships is being done in cooperation with Iran, Oman, all other coastal states in the region, the United States and the maritime industry, according to the secretary-general of the International Maritime Organization, Arsenio Dominguez.

“We have secured the necessary safety guarantees and have thoroughly verified the conditions for safe navigation to support these operations,” he said in a statement.

The organization said moving the ships will be done gradually to avoid any risk of collision.

A shipping insurance executive cheered the development. “That can only be good news for all concerned,” said Marcus Baker, global head of marine, cargo and logistics for Marsh in London.

But the uneasy ceasefire already has been tested by Iran saying it closed the strait again over fighting between Israel and the Iranian-backed militia Hezbollah in Lebanon. Violence again broke out in Lebanon Tuesday.

The U.S. has said that negotiators have discussed “mechanisms” to ensure that the strait remains open. Ship traffic is increasing but questions remain about who controls the passageway.

Data and analytics company Kpler confirmed 39 ships crossed through the strait Monday, after about 92 crossings between Friday and Sunday. Prior to the war, roughly 100 ships a day made the journey.

Two U.S. aircraft carriers were continuing to operate in the Middle East, the U.S. military’s Central Command said.

Iran’s president makes his first visit to Islamabad since the war started

Iranian President Masoud Pezeshkian and Pakistani President Asif Ali Zardari on Tuesday discussed a range of issues, including regional peace and economic cooperation, according to a statement from the presidency in Islamabad.

It was the Iranian president’s first visit since the U.S. and Israel launched war on Iran. He said during a news conference after their meeting that there was no mention of Iran’s missile program in the memorandum of understanding signed between the U.S. and Iran.

“If it was not for Iran’s missile capabilities, our country would have been plundered and destroyed,” Pezeshkian said, vowing to “never compromise or negotiate our missile capabilities.”

Pakistan’s Prime Minister Shehbaz Sharif afterward said he will attend the Tehran funeral of Supreme Leader Ayatollah Ali Khamenei, who was killed in the war’s opening airstrikes.

Iran says negotiations focused on sanctions relief, nuclear issues and more

At the start of a 60-day window to reach a permanent deal to end the war, Iran and the U.S. agreed to create a “de-confliction cell” to address the fighting between Israel and Hezbollah.

Iran said the talks in Switzerland led to the creation of negotiation groups focused on sanctions relief, nuclear issues, reconstruction, and monitoring, according to the state-run IRNA news agency. The report quoted Kazem Gharibabadi, a deputy foreign minister leading the talks there, as saying the countries also formed a way to discuss ships moving through Hormuz.

In southern Lebanon Tuesday, Israeli soldiers opened fire and killed two people. That followed two days of calm after a ceasefire brokered Saturday. Any renewal of heavy fighting could threaten the broader diplomatic talks, since Iran has demanded that a full truce in Lebanon be part of any comprehensive deal.

Israel occupies part of Lebanon and insists it must be able to attack militants launching attacks into northern Israel.

The Israeli military said troops fired at four Hezbollah members who were riding a bulldozer and a motorcycle and had entered a security zone and failed to stop despite warning shots. Lebanon’s state-run National News Agency reported that the two men were killed next to a bulldozer clearing a road.

No Israeli airstrikes or shelling have been reported since Sunday and Hezbollah has not claimed any attacks in what has been the longest halt in the fighting since the latest Israel-Hezbollah war erupted in March.

Netanyahu raises new questions over fragile Lebanon ceasefire

Israeli Prime Minister Benjamin Netanyahu said Monday that his military still has “full freedom of action” in Lebanon to thwart any threats.

Neither Israel nor Hezbollah is a signatory to the U.S.-Iran deal. Netanyahu has vowed to keep his forces in southern Lebanon until threats to Israel are eliminated. Hezbollah has refused to halt attacks unless Israel commits to withdrawing.

When asked about Netanyahu’s comments, Trump said “we’re going to take a look at it,” adding that the situation would “get solved.”

The main highway leading south from Beirut was jammed Tuesday with people displaced from southern Lebanon returning to their homes. Among them was Hawraa Nour El-Din, from the village of Khirbet Selm.

“We don’t want the negotiations done by the government,” she said. “We want Iran to negotiate on our behalf, and we are returning victorious, whether everyone likes it or not.”

In Washington, the State Department said a new round of Israel-Lebanon talks began on Tuesday with both political and security issues on the agenda.
